No and consider yourself lucky. Sperm dies shortly after it hits air. It’s time for you to talk with your girlfriend and the both of you consider some form of “safe sex.”
I won’t say the answer is no; because stranger things have happened, but there is a VERY small chance that you can get pregnant this way. That said, the fact that you would ask this question tells me that you aren’t nearly educated enough to engaging in sexual acts that could possibly result in a pregnancy. Please visit your local family planning facility and speak with a counselor confidentially.
